Have you tested 4.5.7 and 4.6 to see if this was the transition where the bug started?

At this point the system is getting stuck and nothing else can can be done than holding the power button in for a long enough time to turn it off. At the same time as the system get stuck, a red error light is lightening up on the server. This light is green until it reaches this "Starting Reboot" stage. The same happens if the server is shutdown, with the difference that the last message is "Starting Power-Off" instead of "Starting Reboot". The server is installed with a new clean 18.04 installation. This server was rebooting/shutting down without a problem with all releases between 16.04 and 17.10. This problem is serious as it prevents remote reboot. --- ProblemType: Bug AlsaDevices: total 0 crw-rw---- 1 root audio 116, 1 Jun 13 11:16 seq crw-rw---- 1 root audio 116, 33 Jun 13 11:16 timer AplayDevices: Error: [Errno 2] No such file or directory: 'aplay': 'aplay' ApportVersion: 2.20.9-0ubuntu7.2 Architecture: amd64 ArecordDevices: Error: [Errno 2] No such file or directory: 'arecord': 'arecord' AudioDevicesInUse: Error: command ['fuser', '-v', '/dev/snd/seq', '/dev/snd/timer'] failed with exit code 1: DistroRelease: Ubuntu 18.04 HibernationDevice: RESUME=none MachineType: HP ProLiant DL360 Gen9 NonfreeKernelModules: zfs zunicode zavl icp zcommon znvpair Package: linux (not installed) PciMultimedia: ProcEnviron: TERM=xterm PATH=(custom, no user) XDG_RUNTIME_DIR=<set> LANG=en_US.UTF-8 SHELL=/bin/bash ProcFB: 0 mgadrmfb ProcKernelCmdLine: BOOT_IMAGE=/ROOT/ubuntu@/boot/vmlinuz-4.15.0-23-generic root=ZFS=rpool/ROOT/ubuntu ro ProcVersionSignature: Ubuntu 4.15.0-23.25-generic 4.15.18 RelatedPackageVersions: linux-restricted-modules-4.15.0-23-generic N/A linux-backports-modules-4.15.0-23-generic N/A linux-firmware 1.173.1 RfKill: Error: [Errno 2] No such file or directory: 'rfkill': 'rfkill' Tags: bionic Uname: Linux 4.15.0-23-generic x86_64 UpgradeStatus: No upgrade log present (probably fresh install) UserGroups: _MarkForUpload: True dmi.bios.date: 05/21/2018 dmi.bios.vendor: HP dmi.bios.version: P89 dmi.board.name: ProLiant DL360 Gen9 dmi.board.vendor: HP dmi.chassis.type: 23 dmi.chassis.vendor: HP dmi.modalias: dmi:bvnHP:bvrP89:bd05/21/2018:svnHP:pnProLiantDL360Gen9:pvr:rvnHP:rnProLiantDL360Gen9:rvr:cvnHP:ct23:cvr: dmi.product.family: ProLiant dmi.product.name: ProLiant DL360 Gen9 dmi.sys.vendor: HP To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1776616/+subscriptions -- Mailing list: https://launchpad.net/~kernel-packages Post to : kernel-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~kernel-packages More help : https://help.launchpad.net/ListHelp
